1.搜索redis资源

docker search redis

--------------------

2.拉取redis镜像

最好不要拉去 latest 后边版本不好管理 参考：《docker latest标签问题》[https://blog.csdn.net/whatday/article/details/102811821][https_blog.csdn.net_whatday_article_details_102811821]

具体标签可到 [https://hub.docker.com/\_/redis?tab=tags][https_hub.docker.com_redis_tab_tags] 中查找

docker pull docker.io/redis

--------------------

3.查看拉取的redis镜像

docker images

![format_png 1][]

--------------------

4.准备redis的一些配置文件

首先在/root/redis/data 创建好文件夹用于存放redis数据，这个文件夹位置也可以自己选。

然后在/root/redis/ 创建好redis.conf文件。用户redis的配置。redis.conf可以从redis官网下载 然后启动的时候导入redis的配置文件，就可以按照配置来启动了。

mkdir /root/redis

mkdir /root/redis/data

--------------------

5.下载reids配置文件

wget https://raw.githubusercontent.com/antirez/redis/5.0/redis.conf -O redis.conf

--------------------

6.redis配置文件修改

[    ][Link 1]参考《linux redis 配置详解》[https://blog.csdn.net/whatday/article/details/99966518][https_blog.csdn.net_whatday_article_details_99966518]

我的配置是直接注释掉bind

protected-mode yes

其他配置未改动

启动过程中遇到 TCP监听队列长度 警告 修改队列数为511命令： echo 511 > /proc/sys/net/core/somaxconn

参考 《linux 内核参数somaxconn TCP监听队列长度》 [https://blog.csdn.net/whatday/article/details/102963917][https_blog.csdn.net_whatday_article_details_102963917]

--------------------

7.docker 启动redis

docker run -d --name myredis -p 6379:6379 redis --requirepass "mypassword"

docker run --name myredis -p 6379:6379 -d redis:latest redis-server

docker run --name myredis --restart=always -i -t -p 192.168.31.131:6379:6379 -d redis:latest redis-server

docker run --privileged=true -p 192.168.31.131:6379:6379 -v /root/redis/data:/data -v /root/redis/conf/redis.conf:/etc/redis/redis.conf  --name myredis --restart=always -d redis redis-server /etc/redis/redis.conf

-p 6379:6379:把容器内的6379端口映射到宿主机6379端口

-v /root/redis/redis.conf:/root/redis/redis.conf：把宿主机配置好的redis.conf放到容器内的这个位置中

-v /root/redis/data:/data：把redis持久化的数据在宿主机内显示，做数据备份

redis-server /etc/redis/redis.conf：这个是关键配置，让redis不是无配置启动，而是按照这个redis.conf的配置启动

–appendonly yes：redis启动后数据持久化

--------------------

8.启动过程中发现 执行后docker ps 查不到redis 解决方法

--privileged=true 增加权限

如果出现重复name 使用

docker ps -a  查看

docker rm <containerid/names> 移除镜像

/usr/bin/docker-current: Error response from daemon: Conflict. The container name "/myredis" is    already in use by container    8601c55c4aa0965d23c0849aab0a1d49935b1a9ff7232650999b54fe5f2aa043. You have to remove (or rename) that container to be able to reuse that name..

See '/usr/bin/docker-current run --help'.

9.查看启动

docker ps -a

--------------------

10.进入redis

docker exec -ti myredis redis-cli -h localhost -p 6379

--------------------

11.可以配置可视化工具

RedisDesktopManager

官网下载：[https://redisdesktop.com/download][https_redisdesktop.com_download]

github地址：[https://github.com/uglide/RedisDesktopManager/releases][https_github.com_uglide_RedisDesktopManager_releases]

填写完成host及端口号可以点击test connection 测试一下是否连接成功。
